ST. PETERSBURG, Fla. — The Tampa Bay Rays claimed outfielder Daniel Nava off waivers from the Boston Red Sox and optioned outfielder Mikie Mahtook to Triple-A Durham.

The switch-hitting Nava was designated for assignment by the Red Sox on July 28.

The 32-year-old batted .152 in 29 games with Boston this season. He also missed 48 games while spending nearly two months on the disabled list with a left thumb sprain.

Nava hit .267 with 23 homers and 169 RBI over portions of five seasons with the Red Sox.

TIGERS: Dave Dombrowski says there had been no talks with Tigers ownership about a new contract, and as time wore on he began to sense he might not be back with Detroit in 2016.

The Tigers announced Tuesday that Dombrowski’s tenure as president and general manager was ending, naming Al Avila the new GM. The move seemed abrupt, especially because Dombrowski had just finished making a series of trades with an eye toward the team’s future. But Dombrowski was in the last season of his contract, and he says there were no talks about a new deal.

Dombrowski guided Detroit to two American League pennants and four Central division titles. He says it does “sadden” him that the team couldn’t win the World Series during that span.

BLUE JAYS: Right-hander Aaron Sanchez dropped his appeal of a three-game suspension for throwing at Kansas City’s Alcides Escobar in the eighth inning Sunday in a victory over the Royals.

Sanchez was ejected for throwing at Escobar after warnings had been put in place. Umpire Jim Wolf issued warnings after Kansas City’s Edinson Volquez hit Toronto’s Josh Donaldson on the left shoulder in the first.

Sanchez will be eligible to return Saturday, the second game of a pivotal weekend series in New York against the AL East-leading Yankees.

Sanchez began the season as a starter but has pitched in relief since returning from a muscle injury. He’s 6-4 with a 3.39 ERA.

YANKEES: Yankee Stadium visitors soon will be able to avoid long security lines by registering their fingerprints with a biometric identity service used at 12 U.S. airports.

Starting Friday night against Toronto, visitors to Yankee Stadium who register – for free – with Clear will be able to use “Fast Access” entryways to get into the grounds, the Yankees said in a news release. Two other stadiums, San Francisco’s AT&T Park and Denver’s Coors Field, already use the service.

CUBS: Right-handed reliever Rafael Soriano went on the 15-disabled list because of inflammation in his right shoulder.

Left-hander Clayton Richard, signed as a free agent, will work out of the bullpen.

Soriano is 2-0 with a 6.35 ERA in six games for the Cubs after signing as a free agent June 9.

NATIONALS: Pitcher Stephen Strasburg and outfielder Denard Span appear to be moving closer to a return from the DL after good workouts, Manager Matt Williams said.
